HP 4520 Printer will not print black ink.

[Buzzetta]

Mac OS 10.15.6

HP Printer 4250

Issue:  The black ink cartridge was low.  I decided to change it with a brand new ink cartridge.  No black ink printed.  I replaced that cartridge with another cartridge.  Still, no black ink prints regardless of whether I print an alignment page, or print directly from the computer. 

Steps I have taken:

I have made sure the printer software is updated. 

I have replaced the ink cartridges 

I have done a hard shutdown with the ink cartridges removed.

I have done a hard shutdown with the ink cartridges in place. 

What are my next steps short of placing the printer neatly on the curb? 

Please be specific and if you are linking to something please provide the link.   The last time I had an issue with a scanner four years ago, I wound up spending $90 on vuescan software as the HP Easy Scan would not talk to my then current OS.  So if this is some type of software issue, please... I am open to anything.

Hi @Buzzetta,

 I'd like to help! 

To better assist you - 

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or device? 

While you respond to that, let's print a Print Quality Diagnostic page 

1. Make sure to load the input tray with plain, white paper.

2. On the printer control panel, swipe the display to the left, and then touch Setup.

3. Touch Tools.

4. Swipe up on the display, and then touch Print Quality Report.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix the " Print Quality Issues" issue applicable for your printer -  Print Quality Issues 

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.
